Two Sumerian workers build their boat that will eventually be used to carry goods such as food all the way to jewelry or to carry nets and fishermen for fishing. The material they used for some of their boats are bundles of papyrus and/or wood.
OW, dumb splinter.
Even though some boats were used for fishing (Like this one) others were used for transporting goods. As mentioned before they carry fish from the fisherman all the way to imported goods.
Some boats where thought to be used for battles, but there's a chance they weren't used for it.
